GEORG HAYES, OF NE\V YORK, N. Y.

BLIND-SLAT, sec.

SPECIFICATION forming part of Letters Patent No. 335,353, dated February 2, 1856.

Application filed June 29, 1885.

To all whom it may concern:

Be it known that I, GEORGE HAYEs, aresident of the city, county, and State of New York, have invented a new and useful lmprovement in Louver and Blind Slats, with Apparatus for Operating the Same, of which the following is a specification.

My invention consists of a slat for louvers and blinds having a water shed portion, and at anv angle therewith extending inward a perforated iiange or Ventilating portion, the slat being hung by pivots at each side or end, so as to swing outward and inward when operated, and when open or swung outward adapted, by means of the perforated flange to furnish ventilation and a degree of light, which will ofcourse be shut off when the Slat is swung inward in @then-position, affording a complete protection to the interior of the structure in which the slat has been incorporated from leakage or driftage in storms.

It further consists of a combination consisting of two or more such slats, forming aseries, arranged one above the other, constituting a panel suitable for turrets, elearstories, and church-towers; also, in connection with skylightsin their bases or vertical sides, and, also, in ordinary windows, doors, and Verti cal walls of buildings,railroad-cars, marine vessels, die., each upper slat covering and protecting the one beneath, and all adapted to be opened and` closed simultaneously-when open affording protected Ventilation, and when closed absoi lute security against storms.

It further consists of a combination of operating device therewith which will enable them to be opened and closed simultaneously, and securely hold them in any position, as hereinafter described.

In the accompanying drawings, Figure l is a sectional View with conti: ation in perspective, as viewed from below, in order to show the perforated (or apertured)ventilatingflangc below the water-shed. Fig. 2 is a vertical section of one slat. Fig. 3 is a front elevation of the same Slat as Fig. 2, showing the pivots at each end. Fig. 4 is a vertical section of the series of slats, giving their position when closed, and showing the operating device. Fig. 5 is a vertical section of a series of slats equivalent to those of Fig. 4-the only differ- (No model.)

ence, material, is in the position ofthe pivots, they being formed lower down in the slat. Fig. (i is a perspective view of one slat like Figs. l, 2, 3, and 4, showing inside, also the pivots at each end. Fig. 7 is a similar view of the slat as shown in Fig. 5 Fig. S is a View of the lever belonging lo the operating device. Fig. 9 is a vertical section of two slats, showing how they may be molded into ornmnental forms. Fig. il() is a vertical scetion of another modification in form.

A represents the slat formed of sheet metal, such as galvanized sheetiron; or it may be ol' copper. It may also be made of east-iron or other material.

a a represent the pivots, when ofsheet metal, formed by the roll at the upper edge of the Slat, tliepart below being cut shorter, so that they appear as extensions oi" the roll. pivots so formed may be inserted into perforations or holes made in the cheeks of the casing into which the slat is to tit; or other means of hanging may be adopted.

b represents the water-shed portion of the slat, formed without openings of any sort.

c represents the Ventilating portion of the slat, consisting of a perforated or apertnred flange arranged at any suitable angle with regard to the water-shed inside the same, and extending inward far enough to cover the space between water-shed and pivot-roll of the Slat next below when the slat is standing outward to extreme limit desired.

I do not limit myself to size, shape, or num ber of apertures therein; neither to the 1naterial of which this flange is composed. [t may form a part of the same sheet with the remainder ofthe slat or be attached thereto.

d is another flange, bent downward from theventilating-llange or attached thereto. It sets against the pivot-roll7 when the slat is standing out to extreme limit, and serves to protect the joint. It also prevents the slat going farther outwardly, securing the interior against storms entering the joint.

B represents a casing formed to receive the slats, which they fill as a panel. There may be any number of these slats to forni a series for use in turrets, towers, windows, &c.; or the number used may be reduced to one, and such may be set into any suitable casing, and

These A IOO ' form a key, as at g.

they answer as blinds or as louvers, excluding the suns rays While admitting of ventilation.` They also exclude flies, mosquitoes,f Sodi? i The operating deviee eonsistsof a rod,`C, secured to the wall or easing inside by eye attachment in any suitable manner which will permit of its being moved upward and downward to sufficient distance. A lever, D, is formed, as shown in Fig. 8, to serve as a connection between the rod and Ithe slat. lt is Stamped and eut from sheet metal, although it may be cast or otherwise lorme'd. It has an eye or aperture, f, and a portion lel't lo The eye fits over the pivot of the Slat, and tie key [its into the slit between the edges el" the roll, to compel the roll or pivot to turn as the lever D is moved by the upward or downward motion of the rod C. The lever, where in Contact with the rod, has a slot, into which a pin belonging to the rod may operate.

Other means of connecting-the lever t0l the rod may be used, il' desired.

In Figs. 5, 7, and l0 the pivot-roll is farther down the Slat than in the other views. It there forms a molding; but the construction is analogous to the other form described. In that case the flange d lits to the upper edge oi' the Slat.

The flange o1' Ventilating-plate c affords `opportunity of looking out without being observed from without, and may be molded, as shown in Fig. 9.

rBhe small iiange d may be dispensed with,

' which would admit of the slat being thrown glo therewith ali-apertured ventilating-llange,

c, substantially as shown and described.

2. In combination, a series of pivoted and movable louver or blind niais having ray and water shed I), and at an angle therewith, extending inward, an apertured Ventilatingilange, c, eaeh arranged to cover and protect the slat beneath it from leakage and driftage, substantially as shown and described.

3. The operating device comprising rod (i and lever I), olfsi'ainped or east metal, having aperture j", with key g, arranged to fit over the pivots e, substantially as shown and described.
